Built 1809-1812, burned 14 July 1922
Birr Barracks
Lawrence Parsons, 2nd Earl of Rosse, argued for a barracks within marching distance of the Shannon, and Bernard Mullins built it at Crinkill between 1809 and 1812. Under the Cardwell and Childers reforms it became the depot of the Prince of Wales's Leinster Regiment (Royal Canadians) in 1881. Around 6,000 recruits enlisted there during the First World War, and an airfield was added in 1917 - Sergeant John Allan was killed in 1919 when his plane crashed into Crinkill House. The Leinster Regiment was disbanded at independence in 1922, the Irish Army briefly took over, and anti-Treaty IRA irregulars burned the barracks on 14 July 1922. The ruins were demolished in 1985. The random-coursed perimeter walls survive, with gun loops on the north and west and arched gateways with bastion-shaped outer works. A memorial to the regiment was unveiled by its association in 2013.
Offaly's only military burial ground
The military cemetery
When the barracks needed a burial ground, a military cemetery was opened at Crinkill in 1852 - the only one of its kind in County Offaly. A garrison church was built at the same time, doing double duty: divine service at the weekend and a schoolroom for soldiers and soldiers' children during the week. The cemetery served the garrison for 67 years and holds the dead of the regiments that passed through. Roman Catholic soldiers walked up to St Brendan's in Birr for Mass. The local historian Stephen Callaghan has written the full history of the ground for Offaly County Council.
Críonchoill
The name
Crinkill is an anglicisation of the Irish Críonchoill, usually read as the withered or decayed wood - an older, wooded landscape carried inside the name long after the trees and then the barracks came and went.
